To all whom it may concern. 7

Be it known that I, AsArH 'WILDER, a citizen of the United States, residing atByron, in the county of Contra Costa and State of California, have invented new and useful Improvements in Smoke and Fume Condensers, of which the following isa speci-, fication.

' My invention relates to an apparatus which is especially designed to condense and reduce the smoke and fumes arising from combustion in furnaces so that the waste products of combustion may escape in the air without carrying with themlarge quantities of undesirable smoke and fumes.

The invention consists in the combination of a furnace, of draft and ejector attach- Inents by which the direction of the prod-. nets of combustion 1S insured, and in ztSBIlGS of agitating and condensing chambers, with connecting pipes, and an ultimate gasometer or receiver for such products as are not taken care of in the preliminary portion of the apparatus. c

It also includes details of construction which will be more fully explained by reference to the accompanying drawings, in which I 1 Figure l is a general view in partial section of the apparatus. Fig. 2 is a sectional View of one of the condensing chambers;

. ing started; this valve being the valve E is closed.

4 is a blast fan suitably arranged Wlth' directing the blast' into said pipe in such a f way that it acts as an eJector, forming a' As shown in the drawings, A is a furnace of any desired construction, B a'boiler, C a breeching, and D a smoke stack connecting therewith and having within it a butterfly or other valve E by which a passage of the products of combustion through the stack may be arrested and said products turned into the cleansing portion of the apparatus.

2 is a pipe orpassage connecting with the breeching and designed to conduct away the products of combustion therethrough when the valve E is so disposed as to close egress through the stack. WVithin this passage is a butterfly valve or other valve 3 which may be closed, when natural draft through the chimney takes place while the fire is beopened when relation to pipe 2 and having a connection sufliciently strong draft through the furnace and breeching and driving the products of combustion onward through the pipe 2.

This pipe 2 is divided into two branches 2?. By means of a valve 1 theblast may be directedthrough either ofthepassages 2 5+5 are tanks or receivers of any suitable size and each of the pipes 2 connects with the bottom of one of thejtanks. These tanks have within them horizontal diaphragms'or partitions '6 at intervals; these partitions having passages or openings 7 made through them, Within each of the chambers thus formed is a fan or impeller 8 horizontally journaled and revoluble by means of pulleys 9. andconnecting chains 10, powerbeing derived from anysuitable connection by which the fan 1 may also be driven; I p

From the upper part of the chamber 5 a P1136101 passage 11 leads to a receiving or gas tank 12 suitably locatedwith relation thereto. Escape passages or pipes 13 are.

connected with the lower part of the chambers 5 so'that these chambers may be cleaned out at desired intervals. A steam pipe 14 with proper controlling valves, as at 15, is so connected that steam may be introduced either with or without the air blast, at will.

The operation of the device will then be as follows: When the fire is first made and the v apparatusis cold, the damper E in the chimney D may be left open and'a natural draft depended upon until the fire'is suflicientlystarted. This valve is then closed and the valve or damperv 3 in the pipe 2 is opened so that the products of combustion will be diverted into this pipe; At the same time the fan4 being set in motion will form an ejector, driving the fumes through the pipe 2. The valvei being turned to close one of the passages [2 ,the smoke,;fumes and products of combustion will. pass through this pipe and be delivered into the lower part of chamber 5. This chamber is filled with water, supply being brought thereto through the valve supply pipe 13. i

The smoke andproducts of combustion being forced into the lower part of the cham her and. the fans 8 being in motion will thoroughly churn up and agitate the water and enable it to condense any .of the lighter gaseous products, while the heavier carbon forming the smoke will be settled to the bottom; the lowerchamber arresting most all these products and each of the upper chambers arresting successively a less portion while the gas will be discharged through the pipe 11 and into thetank 12.- Whenever it is desired to clean this tank.

Cleansing the tanks.

it is only necessary to change the position of the valve P and thusdivert the smoke be then drawn up or allowed to pass to any further apparatus by Which such gas may be utilized, such apparatus not being here shown.

Suitable pipeand hose connections are made'with the tanks for the injection of Water or cleansing; substances Whenever necessary.

It'will be understood that-the steam pipe M maybe employed'whenever desired either in conjunction Withthe agitator 4 or separately', if desired, and steam may also'be conducted through suitable hose to assist in Having thus described my inventiomvvhat I claim and desire to secure by Letters Pat- 7 cut is- 7 1 In an apparatus of the type set forth, in combination With a furnace, a Water tank,

Copies of this patent may be'obtained for means to conduct the productsof combustion from the furnace to the tank base, a

series of horizontal and vertically spaced partitions in the tank forming top, bottom and intermediate chambers, each of said partitions having an opening at one of its zontal blades arranged so as to sweep adj acent the sides, bottom and top of the respective chambers, said impeller blades having a sweep across points alined with and occurring bothabove and below the respective openings, and means to drive the impellers.

In testimony whereof I have hereunto set my hand inthe presence of two subscribing Witnesses. V V
